Description

Technical Field

[0001] This invention relates to the field of precast component production technology, and in particular to a production equipment for precast concrete components for buildings. Background Technology

[0002] Precast components include precast concrete slabs used in construction. Precast concrete components refer to concrete structural parts that are customized according to different building needs and application scenarios and are prefabricated in a factory or specific location. After being made, these components are transported to the construction site and installed in the building. Precast components include concrete structures such as walls, floor slabs, columns, beams, stairs, and balconies used in the construction process. Precast concrete components require the use of corresponding molds during production and need to be demolded after being made.

[0003] Currently, the production process for precast components manufactured on production lines using molds typically involves several steps: quantitative feeding, shaping, and unloading. However, the long downtime at each stage of the production line and the inability of other steps to operate normally after the downtime result in a series of problems such as long production time and slow output. Therefore, to address these shortcomings, this solution proposes a production equipment for precast concrete components for buildings. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a production equipment for precast concrete components of buildings. This equipment uses a material distribution device to alternately transport molds filled with material to a three-part forming device for molding. The effect is to make the production process of precast concrete components more efficient. By separating the secondary conveyor belt from the primary conveyor belt in the three-part forming device, the traditional method of vibrating precast concrete components directly on the same conveyor belt is changed. By separating them into primary and secondary stages, firstly, the vibration time is effectively extended, making the concrete more uniform in the mold; secondly, it effectively avoids the problem of uneven material distribution caused by vibration transmission to the material discharge end.

[0005] The present invention also provides a precast concrete component production equipment for buildings, comprising a feeding device, a feeding device, a distributing device, and a forming device. The forming device is provided in three sets, and the feeding ends of the three sets of forming devices are fixedly connected to the side surface of the distributing device.

[0008] According to the present invention, a precast concrete component production equipment for buildings includes a pallet with three output ports and one input port. The input ends of three sets of secondary conveyor belts are respectively connected to the three output ports of the pallet, and the output end of the primary conveyor belt is connected to the input port of the pallet. By connecting the three output ports to the three sets of secondary conveyor belts, the precast concrete components are output in separate routes.

[0009] According to the present invention, a precast concrete component production equipment for buildings includes four sets of conveyor rollers. One set of the four sets of conveyor rollers is located at the output end of the primary conveyor belt, and the remaining three sets are located at the input ends of the three secondary conveyor belts. These four sets of conveyor rollers serve as a transition point during the transport of the molds.

[0010] According to the present invention, a precast concrete component production equipment for buildings has sliding grooves on the inner sides of the left and right columns of the gantry frame, and the left and right sides of the lifting plate are slidably connected to the sliding grooves. This facilitates the smooth lifting and lowering of the lifting plate.

[0011] According to the present invention, a precast concrete component production equipment for buildings has a groove on the outer surface of the lifting plate, and the vibrating motor is located inside the groove. This facilitates the installation of the vibrating motor and provides it with operating space.

[0012] According to the present invention, a precast concrete component production equipment for buildings includes a support frame fixedly connected to the lower surface of the feeding valve, and the outer surface of the support frame fixedly connected to the side surface of the primary conveyor belt. This provides effective support for the conveying auger and the feeding valve.

[0013] According to the present invention, a precast concrete component production equipment for buildings is provided, wherein the primary conveyor belt and the secondary conveyor belt are both driven by motors, and the lower surface of the primary conveyor belt and the secondary conveyor belt are provided with support legs.

Multiple molds are provided, and these molds circulate among the primary conveyor belt, the rotary conveyor, and the secondary conveyor belt. This allows concrete to be effectively fed into the molds, and the cyclical use of multiple molds effectively improves production efficiency.

[0015] Compared with the prior art, the precast concrete component production equipment of the present invention uses a material distribution device to alternately transport molds filled with material to three sets of molding devices for molding processing, which makes the production process of precast concrete components more efficient.

[0016] Compared with the prior art, the precast concrete component production equipment of the present invention, through the setting of a three-group molding device, in which the secondary conveyor belt is separated from the primary conveyor belt, changes the traditional method of directly vibrating the precast concrete components on the same conveyor belt during production. By separating it into primary and secondary stages, firstly, the vibration time is effectively extended, making the concrete more uniform in the mold; secondly, it effectively avoids the problem of uneven material distribution caused by vibration transmission to the discharge end.

[0030] Working principle: During use, the mixed concrete is poured into the feed hopper 101. To prevent it from solidifying and clumping, the mixing motor 102 is started to continuously mix the concrete with the mixing rod 107. The conveying auger 105 is started to extract the concrete from the feed hopper 101 and transport it to the feeding valve 104. The feeding valve 104 is set to open and close for a set duration to dispense a fixed amount of concrete. The start and stop of the feeding valve 104 are synchronized with the start and stop of the conveying auger 105. The concrete falls into the pre-prepared mold 202 through the discharge hopper 106. When the mold 202 is full of concrete, the single discharge stops, and the primary conveyor belt 201 operates to transport the concrete to the distribution device 3. At this time, the mold 202 containing the concrete is on the rotating conveyor 302.

[0031] The concrete is sequentially transferred to the molding device 4 via the rotary conveyor 302. When the mold 202 containing the concrete is conveyed to the secondary conveyor belt 401, the linear motor 403, carrying the gantry 404, is at the feed end of the secondary conveyor belt 401. The hydraulic telescopic rod 405 operates, driving the lifting plate 406 to move downwards until the vibrating head 408 on the bottom vibrating plate 407 inserts into the mold 202 and contacts the concrete. Then, the hydraulic telescopic rod 405 stops moving downwards, and the secondary conveyor belt 401 starts running. The linear motor 403 also runs synchronously. At this time, the two run at the same speed and in the same direction. The vibrating motor 409 operates, transmitting vibration through the vibrating head 408 to vibrate the concrete. After the vibration is completed, the vibrating motor 409 stops, the hydraulic telescopic rod 405 retracts, and the linear motor 403 drives the gantry 404 back to the initial end to stop and wait.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
